I'm using JBoss 3.0.3 and am trying to connect to a DB2 database. I'm getting a nested "Failed to register driver for: COM.ibm.db2.jdbc.app.DB2Driver" exception (I won't bore you with the exception listing) when trying to connect to the DB. I've searched the forums for this problem and have followed the steps I found in those searchs, putting db2java.jar in server/default/lib and making sure the DriverClass property was declared on one line. I'm now stumped and am looking for clues from someone smarter than I as to what may be wrong.

According to the start up log, both my db2-service.xml and db2java.jar deployf course a nested exception and I won't bore you with the complete details. Here are excerpts from the log:

Thanks in advance and pardon the rather length post.
